Yokes, what's the difference?

I've had second thoughts about my comments about needing low inductance. Driving it the way I envisioned would be inefficient.

Instead, the yoke probably does look nearly like a pure inductor and the parallel resistors that are added to dampen oscillations from the parasitic capacitance. The transformer will just transform this inductance so that the network of transformer and yoke will just look an inductance. This is then part of the resonant circuit that's being driven.

So the actual value of the inductance of the yoke would be important.

Does this sound right?
